Comment/Description

This course is aimed to provide an overview of the advanced methods of quantum mechanics for the study of many-particle problems in condensed-matter physics. The formalism of the single-particle and two-particle Green’s functions will be introduced and their connections with state-of-the-art numerical methods for electronic-structure theory will be disclosed.
The course is primarily aimed to graduate students with a study and/or research profile in theoretical physics. However, the participation of graduate students and young researchers with an experimental background is equally welcome.
Solid knowledge of quantum mechanics is a must to attend this course. Familiarity with theoretical solid-state physics and with the electronic-structure theory methods is a plus.
